Hair Loss Treatment? Explained Based on Actual Clinical Results. <Cera Exosome, D-tology NMN>

Hello.

I’m Choi Won-woo, a dermatologist with 23 years of experience.

When I see middle-aged patients in my clinic, I often notice that what they worry about even more than wrinkles is their hair.

When they face the mirror and see their hair density has changed dramatically from before, it can affect more than just the sadness of aging—it can also undermine their confidence.

Hair loss that appears at this stage progresses not only because of the genetic factors we commonly know, but also naturally with aging.

Just as skin ages and loses elasticity, our hair also undergoes changes at the cellular level and loses function.

So today, I would like to clearly explain the difference between hereditary hair loss and age-related hair loss, which many people confuse,

and, focusing on the recently drawing attention Cera Exosome procedure, summarize the fundamental reasons why hair becomes thinner and how it can be treated based on clinical results.

  3. The Cera Exosome procedure, a concept of 'rejuvenation' that wakes up cells

  4. Hereditary hair loss and age-related hair loss differ from the start. Hair loss treatment begins by distinguishing the cause of hair loss.

Hereditary hair loss, which is what we commonly know, often starts relatively early, in the 20s or 30s,

and is characterized by progressing in a specific pattern in particular areas.

In men, the hairline recedes into an M shape, or the crown area becomes visibly sparse in a round pattern,

while in women, it usually appears as a gradually widening part line.

This occurs because DHT, converted from male hormones, attacks the hair follicle, meaning hormonal influence is dominant.

On the other hand, 'age-related hair loss,' which is gradually felt from the mid-40s onward, has a slightly different pattern.

Rather than a noticeable loss in a specific area, the main feature is 'hair miniaturization,' where the entire scalp becomes thinner and weaker.

The number of hairs itself does not suddenly decrease, but because the hair texture turns into something like fine down, the scalp appears white and sparse, creating a thin and empty look.

This happens as the function of stem cells within the hair follicle declines with age,

slowing regeneration and lengthening the resting phase, which requires a different approach from hereditary hair loss.

  1. I’ll explain why hair becomes thinner. As people get older, many assume that hair thinning is simply due to insufficient nutrient supply and rely only on supplements.

However, from a medical perspective, the fundamental cause is not the nutrients themselves, but a disruption in the 'intercellular signaling system.'

Hair follicles are dynamic tissues that continuously repeat the cycle of growing, shedding, and regrowing throughout life.

But as aging progresses, the growth signals that tell the hair to stay thick and strong are not delivered properly, and instead, signals to stop growing begin to become stronger.

In this process, the size of the hair follicle gradually shrinks and becomes smaller, and thick terminal hairs turn into thin, weak vellus hairs.

In addition, stem cells around the hair follicle are exposed to repeated oxidative stress and DNA damage, causing them to lose their original regenerative ability.

As a result, hair stops growing before reaching a sufficient length or falls out,

and even melanin production decreases, leading to loss of luster and a dry, rough texture.

In the end, age-related hair loss is not simply a change in appearance, but the cumulative result of these cellular functional declines.

  1. The Cera Exosome procedure is a concept of 'rejuvenation' that wakes up cells. Hair loss treatments up to now have mainly relied on drugs that regulate hormones or expand blood vessels.

These methods can be effective for hereditary hair loss, but they have limitations when it comes to reversing hair loss in people in their 40s and 50s, where cellular aging is the main cause.

Cera Exosome actual clinical results

As an alternative, the Cera Exosome procedure has recently been drawing attention.

Among microbiome-derived exosomes, Cera Exosome has advantages in scalp penetration and cellular delivery,

and focuses on penetrating deep into weakened hair follicles to deliver the signals needed for growth again.

Rather than a purely defensive concept of simply suppressing hair loss progression, it is an active direction of 'regeneration' that reactivates the environment of hair follicles that had been dormant due to aging.

We are also studying ways to enhance the synergy by using 'D-tology NMN' together with it.

NMN is a precursor that produces NAD+, which is necessary for cellular energy metabolism in our body,

and acts as fuel that helps aged cells use energy efficiently again.

To put it simply,

if Cera Exosome prepares the soil so hair can grow well and serves as a seed, then NMN is like supplying the energy that allows that seed to sprout.

As shown in the clinical photos, it is actually showing the effect of new hair growth.

In closing, Cera Exosome procedures aim to reorganize the scalp environment where hair has become difficult to grow.

With the combination of D-tology NMN, they help support these changes by improving efficiency inside the cells.

Of course, we cannot guarantee the same results for every hair loss patient,

but if you have not seen results from existing treatments or have reached a point where your hair is gradually weakening and the change has plateaued, please consider it carefully.

Hair loss is no longer something that must simply be hidden or accepted as part of aging.

With the help of medical care and consistent management, you can maintain a much younger and healthier appearance.

I hope today’s post was of some help with your hair concerns.^^

Thank you for reading this long post.

This was Dr. Won-woo Choi, Chief Director.
